SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 762,595, dated June 14,1904.

A lication filed December 12, 1903. Serial No. 184,901. (No model.)

citizen of the United States, residing in the city-and county of SanFrancisco and State of California, have invented new and usefulImprovements in Sash-Locks, of which the following is a specification.

My invention relates to an improvedappliance for securely lockingtogether the upper and lower sashes of windows.

Its object is to provide a cheap, simple, du-

rable, and attractive device which may be attached to either side of anysash to lock two sashes together and prevent their rattling and whichwill' permit the upper and lower sashes to be locked together, eitherwhen closed or when opened, and when so locked together in any desiredopen position the size of the opening cannot be enlarged by any one onthe outside.

It consists of the parts and the construction and combination of partshereinafter more fully described, having reference to theaccompanying'drawings, in which Figure 1 shows my device applied to awindow-sash. Fig. 2 is a detail of an individual socket. Fig. 3 is adetail of a' socket-plate. Fig. A is a detail of a rock-shaft. Fig. 5shows a modification.

A represents a plate adapted to be secured to the upper rail of thelower sash adjacent to one side or the other of the window-frame. Anunincased rock-shaft or bolt 2, having a longitudinal sliding movement,is suitably journaled in standards 3 on the plate and is adapted to bemoved in and out by means of the arm 4 to engage the gimlet-pointedscrewthreaded socket-pieces 5, which are disposed in line in the siderail of the upper sash at suitable intervals.

The arm L carries a projection 6, which is intended to engage inperforations 7 8 in plate A to hold the shaft against longitudinalmovement.

Each socket contains a rubber bushing 9," against which the end of theshaft 2 is adapted to abut and prevent the window rattling when theshaft and socket are in engagement and the sashes in locked position.The sockets are adjustable relative to the movement of sashes.

the rock-shaft by means of a screw-driver engaging the notches 10.Consequently whenever the rubber packing 9 becomes compressed and thereis any tendency on the part of the sashes to rattle suitablereadjustment may be made.

By having a number of socket-pieces in the upper sash either sash may bemoved relative to the other and locked at any position, so as to provideventilation at top or bottom of the window or at both top and bottom.Furthermore, so long as the sashes are thus locked together theVentilating-space cannot be enlarged by any one from the outside. Thelock is secure against being tampered with through the medium of aknife-blade, wire, or other instrument passed up between the Accordinglywith windows so safeguarded from marauders lodgers may feel secure inopening their windows for suitable ventilation even where rooms are in amore or less exposed position.

It is to be noted that the ends of the shaft or bolt 2 are symmetricaland that they each have substantially the same amount of movementoutside of the standards 3, in which the shaft is journaled. Thisrendersthe device interchangeable, so that it may be applied to either right orleft of a sash. Hence the reason also for providing the double set ofnotches 7 8.

By having the bolt somewhat elevated from plate A and unincased itpermits the operator when standing on the floor to see a socket abovethe edge of the top rail of the lower sash and not make it necessary tohunt around blindly with the bolt to find the socket.

In lieu of the individual socket-pieces 5 I may employ a plate, as 11,(shown in Fig. 5,) having the projecting lugs 12 for attachment .toeither of the side rails of the upper sash and provided with sockets orpockets 5' at suitable intervals. These sockets would like- Wise containa resilient packing material 9, as rubber, to prevent rattle when thesashes were locked together. This idea of interchangeableness, wherebythe device is indiscriminately applicable to one side or the other ofthe window, is an important feature of the present invention.

Having thus described my invention, what 2.
